Project SIREN: advancing networked sensing through collaboration

For the first time in the , the Defence Science and Technology Laboratory () has successfully demonstrated advanced radar signal processing and sensor fusion across multiple air platforms as an enabler for faster and more accurate detection.

Collaborating with industry and academia

The demonstration is an important achievement of Project (System for Integrated Radar Early-response Networking) which directly supports the 's future integrated air domain sensing capability. The outcome demonstrated the power of collaboration with industry and academia, marking a major step toward future integrated sensing capabilities.

Funded by the Chief Scientific Advisor's research programme, this science-led initiative shows the 'One Defence' mindset which is central to the Strategic Defence Review 2025. By uniting government scientists, industry partners, and academic researchers, the consortium moved from concept to demonstration in just 15 months, finishing in a series of airborne experiments off Scotland's east coast in May 2025.

The joint academic and industry team successfully integrated multiple radars to produce a near real-time picture of the air and maritime environment. These technologies promise to significantly improve situational awareness and tracking - something which is vital for modern defence operations.

An important step was the fusion of data from distributed sensors using cloud-based integration, linking airborne systems with ground stations. This lays the foundation for future multi-platform sensing across defence, and supports the 's emerging Digital Targeting Web, which enables rapid coordination from sensor to decision-maker.

Who the project brought together

The project brought together expertise from Leonardo, Igence Radar, Voyant and academic partners from the University of Edinburgh and University of Liverpool. provided leadership and technical guidance, helping to align commercial and academic innovation.

This model clearly shows how collaboration between government, primes, and academia can harness best-of-breed capability, accelerating development through to exploitation and strengthening the defence enterprise.

Benefits of

offers cutting-edge technology into the hands of our armed forces faster. It has generated valuable intellectual property and technical capability that will inform future defence programmes. The consortium's knowledge, tools and expertise are now being applied to better understand the value and advantages of networked systems as part of the future force mix.

Building on the progress made by , work is now focused on transitioning to an exploitation footing, targeting both spiral development options for existing platforms as well as new and novel implementations.
